^^^ Good advice.
Food is your greatest weapon for the first few days. Eat an early dinner, and eat so much you're going to barf.
Remember how when you're on a tear, you can skip a meal, or that the tear stops after you eat?
Yup, works well for quitting drinking too. I recommend either Pizza Ranch or Golden Corral, depending on where you're located.
Plus, it is a change of pace, and knocks you out of your daily drinking routine.
